Spring clip automatic assembly machine

Abstract

The invention relates to a spring clip automatic assembling machine. The machine comprises a rack. A clamping plate splicing unit, a torsion spring compression unit and a pin insertion unit are arranged on the rack. The clamping plate splicing unit comprises a clamping plate splicing seat which comprises two opposite clamping plate clamping seats. Clamping plate body location cavities and pivoting lug stretching ports are formed in the clamping plate clamping seats. The two clamping plate clamping seats are arranged at an interval to form a pivoting lug splicing spacing cavity for a clamping plate upper pivoting lug. The pivoting lug stretching ports are communicated with the pivoting lug splicing spacing cavity and the clamping plate body location cavities. A spring clip blanking port communicated with the clamping plate body location cavities, the pivoting lug stretching ports and the pivoting lug splicing spacing cavity is formed in the clamping plate splicing seat. The pivoting lug splicing spacing cavity comprises a torsion spring feeding port in corresponding fit with the torsion spring compression unit and a pin insertion port in corresponding fit with the pin insertion unit. By means of the machine, the spring clip automatic assembly machine is provided, and the assembly efficiency and the finished product yield of spring clips are improved effectively.

Description

technical field [0001] The invention relates to an automatic equipment, in particular to an assembly machine for assembling and forming spring clips. Background technique [0002] Spring clips are common articles in people's lives, and their uses and types are also relatively wide, such as hair clips for clipping hair, book clips for holding books and paper, etc. like figure 1 Shown is an existing common spring clip 9, including two splints 91, a torsion spring 93 and a pin 92, the splint 91 includes a plate body and a pivot seat, the plate body includes a clamping portion 911 and a pressing portion 912, pivotally mounted It is seated at the junction of the clamping part 911 and the pressing part 912. The clamping part 911 and the pressing part 912 form a seesaw structure with the pivot mount as the fulcrum. The pivot mount is composed of two opposite pivot mount ears 913. The pivot mount ears 913 There is a pin insertion hole 914 on the top, wherein, the plate body formed...

AI Technical Summary

Problems solved by technology

[0003] At present, the spring clip 9 of the above-mentioned structure is manually assembled, the operation is relatively complicated, and it is difficult to master it, thus affecting the production efficiency, and the torsion spring needs to be loaded in a compressed state to ensure the clamping force of the spring clip and the compression amount of the torsion spring. It is difficult to control, it is difficult to ensure that the clamping force of each spring clip is consistent, the quality stability of the clip is poor, and it is easy to cause problems such as torsion spring protruding, hurting people, losing, and splint breaking, resulting in high scrap rate and production safety problems
